1. If the owner replaces the high beam with an led light, but does not add a lens, it will not be able to gather light. When driving at night and turning on the led light, it can't bring better effect.
2. In fact, compared with halogen lamps, led lamps have completely different luminous points, in which the light emitted by led lamps is completely scattered, so it is necessary to install lenses to better concentrate light.
However, if you choose a full led headlight, it will have a lens itself, and the light pattern will be better and the brightness will be good, thus solving the problem of light gathering.
3. Generally, when driving at night, the low beam will be used more frequently, especially on roads with good lighting. Turning on the low beam directly can make the vehicle run smoothly.
Some cars leave the factory with halogen lights, some have xenon lights, LED lights, and some even have laser headlights. The lights can be modified if they meet the requirements. The color cannot be changed. The light is either mainly white or mainly yellow. If the headlights are halogen lamps from the factory, they can be changed to LED or xenon lamps with lenses or laser headlights.
But there is still a requirement that the maximum brightness of the lights on each side cannot exceed 120,000 candelas. For a diffuse scattering surface, although the light intensity and luminous flux in each direction are different, the brightness in all directions is equal. The fluorescent screen of a TV is similar to such a diffuse scattering surface, so the image has the same brightness when viewed from all directions. Modifying car lights to increase the brightness will significantly improve the safety factor of driving at night. The lights are bright enough, the illumination distance is far enough, the paving width is wide enough, and there is more sufficient reaction time when encountering road emergencies. It is best to choose a regular lamp modification shop to modify your car lights!
